| 摘 要： | 提出了一种新的弹道目标特征提取方法:对宽带雷达回波进行STRETCH处理后用ESPRIT方法估计其中频点,然后采用Gerschgorin半径方法进行散射源数目估计,去除虚假频率,获得目标散射点的数目、位置、散射中心强度等特征参数。与基于FFT算法的特征提取方法相比,这种方法具有更强的抑制杂波能力和更高的分辨率。仿真结果表明了该方法的有效性。

| Abstract: | A novel approach of extracting the high (resolution) (signatures) of the (ballistic) (target) in (midcourse) is (proposed). This method (processes) (high-resolution) radar echo by using (STRETCH) and (extracts) the (signature) of the (target) by using (ESPRIT), (including) the (position) and (intensity) of (scattering) centers. (Then), the (method) of (Gerschgorin) radii is used to (estimate) the number of scattering (centers) for (removing) the (illusive) (frequency) dot. (Compared) with the FFT (algorithm), this (approach) (possesses) (higher) (resolution) (power) and can (suppress) the (clutter) (more) (effectively). (Simulation) (results) (verify) the (effectiveness) of the (method). |
